Data Summaries

Bootstrap Grid View allows you to display a summary, i.e., brief information about groups of rows or individual data columns. For example, you can use a summary to display the number of records in the data sample or the maximum column value.

Custom Summaries

There are five predefined aggregate functions that you can use to calculate summaries: Sum, Min, Max, Average, Count. However, in complex use case scenarios, you may want to calculate a summary based on custom logic. Set the summary item's ASPxSummaryItemBase.SummaryTypeproperty to Custom, and handle the Grid View control's ASPxGridBase.CustomSummaryCalculate event to achieve this goal.
